80 because you find the area of the triangle and subtract it from the area of the rectangle to get 80
Answer:
48.8°
Step-by-step explanation:
We solve using sine rule
The formula is given as
p/sin P = r/sin R
In APQR, P = 83°, p = 285 m, r = 216 m.
Calculate R.
Hence, solving for R
285/sin 83 = 216/sin R
Cross Multiply
285 × sin R = sin 83 × 216
sin R = sin 83 × 216/285
R = arc sin (sin 83 × 216/285)
R = 48.78527°
Approximately = 48.8°
Therefore, R = 48.8°

Answer:
6.0.
Step-by-step explanation:
The line marked 20 is 2 times the line marked 3x - 8 (because the last line cuts the 2 sides of the large triangle in 2).
2(3x - 8) = 20
6x - 16 = 20
6x = 36
x = 6.0.
